What is the measure of angle X ?
A. 147
B. 33
C. 100
D. 60

Answer:
the answer is a. 147
Explaination:
A triangle always has a sum of 180°.
We already have the angle of two sides give.
10° and 23°
To find the last missing side, you add 10° and 23°, and minus the result from 180°.
10+23= 33
180-33 = 147
Triangle =180 degrees
Add 10 degrees with 23 degrees
10+23=33
180 degrees -33 degrees
Answer:
A. 147 degrees
